To the intent that now to the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,Ephesians 3:10

This is not speaking of the plastic, man-made, church, but the scriptural church that is being built according to the pattern. It may be incomplete, not fully assembled, and imperfect right now, but God is building a House. That House, with many "abiding places," is His Church, His Called Out Ones.
